Objectives
  • Development of a basic binder system for various materials, e.g. ZrO2, Al2O3, SiC, Porcelain
  • Reduction of debinding time and improvement of process reliability
  • Manufacturing of complex parts with tight tolerances (< 1 %)
  • Reduction of post sintering grinding costs by near net shape processing
  • Realisation of microstructures

Methods

  • Chemical surface modification of powders for tayloring rheology, high solid loading homogeneity
  • Investigation of correlation between rheological properties and performance of compounds
  • Debinding by thermic, solvents or supercritical media

 



Results
  • Compounds with m m and nano scaled powders
  • Very short debinding times (part depending, up to 30 min)
  • Environmentally sound processing conditions due to binder recycling
  • Thight tolerances can be met

Applications

  • Complex engineering and functional parts
  • Enhancement of manufacturing productivity of traditional silicate ceramics (z.B. porcelain cups with handle)
  • Microstructural applications e.g. medical devices (endoscopy) and electronic industry

Benefits

  • Reduction of post sintering grinding costs
  • Economic production of mass products
  • Sole technology for the manufacturing of very complex shaped ceramic structures
